You will need to open the film cartridge and transfer it to a film processing tank in complete darkness. You can do this in a film change bag or use a blacked out bathroom/closet. After this the rest of the process is done with lights on. You will need film, developing chemicals and a sink. Processing can take about 25 minutes and another 30 minutes to hang your film to dry. Processing times will vary with temperature, film type and speed. You can process multiple rolls within the same time with larger tanks.
